Description
Technical Field
The utility model relates to a vehicle start field especially relates to a vehicle intelligent key does not have emergent starting drive of electricity.
Background
After the electric quantity of the intelligent key is consumed, emergency starting can be carried out through the controller ECU, the key and the one-key starting switch, wherein the one-key starting switch integrates the IMMO coil and the LIN communication base station, and the intelligent key integrates the Transponder. The anti-theft coil generates an alternating magnetic field around the Transponder, so that an LC circuit inside the Transponder generates voltage to supply power to the Transponder, the Transponder sends a modulation signal containing key information to the anti-theft module, the carrier frequency of the signal is 125khz, and an amplitude modulation (ASK) technology is adopted. The signal is received and demodulated by a base station in the anti-theft module, the anti-theft base station analyzes the signal and sends the result to a controller (PEPS) through a LIN line for key authentication.
This approach has the following problems:
1. the assembly position of the one-key starting switch is not fixed, and the key needs to be tightly attached to the starting switch by hand during emergency starting, so that the operation is inconvenient;
2. the induction distance between the key chip and the one-key starting switch is strict, the requirement is not less than 10mm, and the experience is poor;
3. the special requirements of the IMMO coil limit the modeling of the one-key starting switch, so that the modeling of the switch is not attractive;
4. the one-key starting switch integrates the IMMO coil and the LIN communication base station, so that the cost of the switch is increased;
5. the success of the induction authentication of the key chip and the IMMO coil is not high, and is about 70%.
